Flu

Veterinarians are warning about a highly-contagious dog flu virus that's spreading across the country. The strain, known as H3N2, has sickened at least 2,000 dogs in 40 states since last spring. It most recently cropped up in Missouri, and Texas before that.

There are concerns, especially in southern states, about an outbreak of H1N1 swine flu. At least five deaths have been reported in Texas, with widespread cases seen in Louisiana, Mississippi, Alabama and near St. Louis. Swine flu was blamed for about 12,000 U.S. deaths in 2009.

The government wants U.S. residents to heed a health warning issued by the CDC as the agency looks into a mysterious outbreak of a stomach bug. The illness, called cyclospora, is reportedly affecting upwards of 250 people across at least six states.
